Calculate the determinant of this matrix:
What is the first step?

Step 1: Augment the matrix by copying columns 1 and 2 to the right of the matrix

Step 2: Find the products along the main diagonals
d1= 4
d2= 0
d3= 3

Step 3: Find the products of the minor diagonals
e1= 0
e2= 16
e3= 2

Step 4; Perform the final calculation

d1+d2+d3-e1-e2-e3= -11
